I just figured out today, how to see satellite footprints on Lyngsat website:
the rightmost column in the tables for frequencies, says either "ConUS" or
beam direction, like "Americas". If it's a link, it will bring you the footprint map.
Whatever is with number 48 and up for your area, is a good signal.
Sadoun site has a table of these numbers "EIRP values vs. Dish Size"
